> How we can extract just videos?Unless you have the urls, you can't JUST get
anything. You MUST let it spider the site (get the html) to get them.

Most vid/audios are downloaded via a application (SWF). HTT will get the SWF
but the flash will try to play the media from your machine which won't exist.
HTT can only do it if the media url is on the page (and you used Attempt to
detect all links)

Generally, you can't.
